This invention relates to 4sprinklers ysuch as are arranged ,to be mounted in connection' With underground Water systems to lWateri 'large areas, such as park laWns,jgolf courses f f5 andthe like.v n

' kOne ofthe major objects ,invention is to providek a sprinkler-'of' the LopY posed-nozzle reaction-rotation,type,-,vvith a means so r-that the kWater passing through the ia sprinkler head and beforefreachi'ng the nozv 'zles, Will positively rotate the'head independ- 2f ently ofthe rotarymotion imparted therge i y, theseparate rota' i to 'by reason of saidffopposed nozzles.

A further object is to ay sprinkler.v y vor disappearing type (that 25 is one Which drops of itself'so-that it `isfliushV of the telescopic with the ground When'th'e Water is turned off) having this positive rotation structure arranged in connection therewithso that thea? be positively rotated as., v '30 soon as and only When-'it lifts to its proper operating position under thefinfluence of;the This Q feature n permits a greater range:A

The cap 4 yis then hori- 'Zontally alined with a pluralityof inwardly projecting vertically alinedribs or -vanes 122' f Y' formed in the body. The water issuing tantive V*to the cap-passages, and vertical vanes projecting inwardly from the head just above the lower spindle-engaging portion thereof and arranged to have a running fit with the ends of the cap and tolie in the horizontal plane of the cap passages when the head is raised to its full extent onfthe spindle.

F rom the foregoing description it will be readily seen'that I have produced such a depressure available and other condi- Y the-inventionas set forth herein..V e n While this specification sets forth 'in' de-V 1 tail the presentand preferred construction V of the device, still in practicev such deviations,
